Title: Active matrix substrate and method for manufacturing the same as well as liquid crystal display device
Inventor: IZUMI YOSHIHIRO
IPC: G02F1/1343
Filed: 2000-10-06
Abstract: PROBLEM TO BE SOLVED: To drastically shorten a manufacturing process for pixel electrodes. SOLUTION: The pixel electrodes 22 may be formed by using a sol-gel material and applying this material by a spin coating method or dipping method without using a vacuum deposition device, by which the manufacturing process may be shortened. At this time, the pixel electrodes are formed prior to the formation of signal electrodes 23, signal wiring and TFTs 24, by which the impartation of thermal damage to the pixel electrodes is averted even if the heat resistance temperature of the electrode wiring and the TFTs 24 is about 350 deg.C. Further, a photoresist patterning process step and an etching process step at patterning may be eliminated and the process may be shortened by using the sol-gel material having the photosensitivity. The equipment investment relating to the manufacturing apparatus may thus be reduced and the cost reduction of the active matrix substrate itself may be realized.
